On 1 July 1991 the former Finnish prime minister Harri Holkeri made the world’s first GSM call, calling the deputy mayor of the city of Tampere. That was 30 years ago.

This “back to the future” July edition pays tribute to the big bang that GSM brought in ICT. Of course, GSM was one of the first success stories of ETSI and one of the reasons why we were set up in the first place, but more importantly it was going to benefit the world’s population, facilitating global access to mobile communications. With 2 billion GSM connections in 2006, and more than 5 billion unique mobile subscribers to date*, GSM laid the foundations of the ICT landscape and its standards as we know today.

To revisit part of the GSM story and understand how it shaped the future, we have asked the pioneers of these exciting times to give us their insights. In The Interview Stephen Temple, who drafted the GSM MoU, recounts the story as he experienced it and outlines his view of the GSM legacy. Chris van Diepenbeek, Chair of the first committee for Radio Equipment and Systems, leads us on a journey to the CEPT. Klaus Vedder, Chair of our Smart Card Platform committee shares with us the start of a second ETSI success story, the SIM card, and its evolution, while Kevin Holley, the former ETSI Chair of the data services group

This edition pays tribute to the big bang that GSM brought about in ICT.

within the GSM committee, reminds us of the SMS invention, yet another form of communication GSM enabled.

In the Spotlight section, I outline why without GSM, we would probably not be talking about 5G or 6G as we do today and how this mobile system set the foundations of the current international standardization principles and its ecosystem. Zemin Yang, the former Secretary General of China Communications Standards Association (CCSA), granted us an exclusive interview on how GSM shaped China’s telecommunications and contributed to today’s innovations. In our New Member Interview, Magister’s CEO, Tommy Flink, bridges the gap between “earth” and “space” to enter the 6G era.

But there’s more for you to read - our cooperation agreement with O-RAN Alliance, the start of 3GPP and our 2021 new fellows to name a few.

When younger people around you talk about 5G, now you can tell them how it all started!

Recently, the thoughts of the Technical Specifications Groups (TSG) in 3GPP have turned to the prioritization process for the

3GPP new marker next two years, as Release 17 features move towards their scheduled completion by June 2022.

From Release 18 onwards, the Partners have agreed that a new 5G-Advanced logo will be shown on the cover sheet of Technical Reports and Specifications. The new release will further evolve features and use cases identified for 5G, justifying the creation of this mid-generation marker.

Recently, the RAN TSG held its Workshop on the new radio features for 5G-Advanced, ending on 2. Details of the outcome of that event are the focus of a recent news article at www.3gpp.org. In parallel, 3GPP TSG SA has made progress on their studies for Release 18 – which will also carry the new 5G-Advanced branding and they too will hold a Release 18 workshop, starting on 9 September.

Stephen Temple was a DTI Official who wrote the GSM Memorandum of Understanding that committed European mobile operators to support the GSM standard and roll out GSM networks by 1991. He wrote the DTI Consultation Document Phones on the Move, that extended GSM’s use to the 1800 MHz band for small hand portables and widely recognized as

having triggered the transformation of the mobile phone into a mass-market consumer product. He led the UK’s role in setting up ETSI and was elected as the first Chairman of its Technical Assembly. He has been involved in every generation of cellular mobile technology, created the concept of 5G pioneer frequency bands and recently edited the IET Guide 6G for Policy Makers.

Stephen Temple

What was the main driver for the GSM project? The main political driver for GSM was to find a solution to the great European problem of the time – fragmentation due to countries adopting different mobile technologies and different frequency bands. If somebody had wanted to drive across Europe and stay in contact, their car would have been so full of radio boxes that there would have been no room for any passengers. Even worse was the likelihood of being stopped at a border and told that foreign car phones were illegal.

The first analogue phone to fit in a shirt pocket (shown above) arrived in 1986, giving GSM a huge competitive mountain to climb upon its launch in 1991.

In this exclusive interview,

Stephen Temple reveals the

exciting GSM story and its

legacy thirty years later.

It was ‘the problem of the age’ that GSM was required to solve rather than addressing any shortcomings of 1G technology. Indeed, several 1G analogue networks were quite good. The first analogue mobile phone to fit in a shirt pocket had arrived five years ahead of the launch of GSM in 1991. The market alone could not have got GSM off the ground against competition from rapidly advancing analogue cellular technology.When politics gets mixed up with technology standards things usually take a turn for the worse. But in this case, it was ‘good politics’. GSM had a strong ethical dimension of openness, balance of interests and everyone pulling together to expand the public good. I am reminded of this today when I hear some research leaders calling for 6G to address the great societal challenges of today’s age.

What role did ETSI play in GSM’s success?The big driver for creating ETSI was to bring manufacturers into a balanced partnership with telecoms network operators in setting telecommunications standards. GSM was ETSI’s first flagship project and test case for this super-national network and customer-supplier partnership. Success required the largely monopolistic network operators to change their mindset. They had to look beyond national advantage and align their technology goals and, in doing so, bring their industry supply chains into line with the shared goals. The success of GSM and every subsequent mobile generation flows from this alignment of

network technology innovation goals by many ‘customers and suppliers’. Such focus unleashes enormous economic forces. The involvement of manufacturers in GSM standard setting also occurred just in time. A high degree of professionalism was introduced that allowed ETSI to produce thousands of pages of GSM technical specifications to support the launch of GSM by 1991. That professionalism has endured.

How did GSM cooperation manage to endure when so much competition was unleashed with the launch of GSM?It is true that the GSM spectrum was used to implement a competition-based mobile network market across Europe. Enormous thought went into drafting the GSM Memorandum of Understanding on where close cooperation was essential and where competition was paramount. Cooperation was to be total in the ‘cake baking’ phase and competition paramount in subsequently fighting

for ‘the largest slice of the cake’. This delineated ‘pre-competitive’ phase for mobile generations allowed a friendly coming-together of engineers from competing companies for collaborative research and standard setting. Such a thoughtful mix of cooperation and competition underpins today’s phenomenally successful global mobile industry.

What other aspects of the GSM legacy do you still see today?The main one is the timing and synchronization of mobile generations. The GSM Memorandum of Understanding synchronized the procurement cycles of a large number of mobile network operators. Then a very deliberate decision was taken by ETSI officials to frustrate any chance of the UMTS wideband technology arriving too early to become a competing standard. UMTS was a third-generation technology by design. Yes, it was ETSI that established the ‘G’

approach to mobile network technology advances. It was an inevitability that 4G would become a next-generation innovation, in spite of efforts to call it a long-term evolution. The marketing value of the ‘G’ label was just too good to ignore. 5G picked up on the pattern and was made a next-generation technology by design.

What has been lost from the GSM legacy?A major GSM success was SMS messaging. A high degree of cooperation between mobile operators made this possible. This level of cooperation over ‘new public services’ fizzled out with 3G. It has left the mobile operators doing the heavy lifting for mobile infrastructure and the tech giants largely enjoying the fruits of new services. As a result, the ‘G’ business model is becoming ever more challenging.

Do you see this GSM legacy enduring? As 5G has been such a roller coaster, people have asked – does the world need another ‘G’? I have given this some thought. ETSI’s creation of the ‘G’ approach for GSM invented a tool that addresses a particular class of competitive market ‘innovation failure’ for interoperable networks, where nothing can happen unless an entire industrial ecosystem acts together. But the question about the arrival of 6G is academic, as the momentum towards 6G appears unstoppable. What remains wide open for debate is its shared goals. The best traditions of ETSI’s GSM legacy would be for ETSI to support the call for these shared 6G goals to have a global focus on addressing the great societal problem of today.

Dedication: To my three comrades-in-arms who were with me navigating the political choppy waters in the run-up to the 1991 GSM launch – Philippe Dupuis (France), Armin Silberhorne (Germany) and Renzo Failli (Italy), and to Thomas Haug (Sweden) who captained the GSM ship into calmer ETSI waters whilst all this was going on.

“GSM was ETSI’s first flagship project and test case for this super-national network and customer-supplier partnership.”

“The main political driver for GSM was to find a solution to the great European problem of the time: fragmentation.”

“The mix of cooperation and competition underpins today’s phenomenally successful global mobile industry.”

“The main legacy is the timing and synchronisation of mobile generations.”

Magister has evolved with the market’s requirements – what were the main milestones?

Since the company was founded in 2005, we have been developing network-level simulators that incorporate users, devices (terminals, base stations, controllers, core network), radio access technology and services. Simulators allow companies to benefit from detailed, realistic modelling for their wireless system behaviour, interactions and protocols without investing in prototypes or commercial systems. They proved very useful, e.g. for 3GPP standardization activities.

Tommi Flink, CEO of Magister Solution, tells us

why SatCom network simulations help the telco

ecosystem evolve into the next generations of

telecommunications.

Tommi Flink has more than 20 years of experience working in the ICT industry, many years of which were spent on financial industry products and services. Mr Flink received his MSc degree in computer sciences from the University of Jyväskylä in 2001. He believes that

aspects such as a high level of usability and service-based delivery models will also become more and more important in B2B services, and at the same time emerging technologies like Artificial Intelligence and Blockchain will have a major impact on the world around us.

It is important for companies to develop their own area of expertise and the best possible way to create value for their partners and customers at Magister Solutions is to provide world-class SATCOM network simulations.

For about 10 years, we have been involved in several European Space Agency (ESA) activities, developing network simulators for the European SatCom industry. Then, in order to be able to provide more value to the industry and productize our extensive knowledge of system simulations, we went one step further and developed a service through which we are able to offer network simulations with built-in analytics, visualizations and scalable cloud computing. So instead of providing, for example, an open-source simulator delivered to ESA, which might not be used outside the project, we offer a new service, targeting the whole SatCom industry.

As an independent vendor, instead of building only customer-specific “black box” solutions, our goal is to productize our services for a wide range of customers. It enables the execution of reliable simulations without extensive development processes, even for the companies without a dedicated team and long history in such simulations.

Why was it important to develop this software as a service for the satellite industry? Didn’t they already have simulators?

As you know, satellite communications are becoming more and more complex with, for example, the co-existence of multiple wireless technologies. It will also grow with the introduction of 5G Non-Terrestrial Networks (NTN) and new players entering the market like Amazon or Space X. Most satellite vendors and these newcomers play an active role in ETSI and 3GPP standardization, but they need the network simulation capabilities and

simulation results as part of standards studies.

In the past, simulators produced for customers directly or within the ESA project have been very difficult to use. In the mobile industry, large companies might have their own R&D teams or subcontractors. As we have built several validated simulators in the past, we have harnessed this experience to provide the SatCom industry with an alternative independent, vendor-neutral and user-friendly solution. And this expertise is used in the standardization world, in the RAN 3GPP group for instance, which is very important for us.

Standardization seems to be essential for your activities – is this related to the development of your 5G network/system simulator?

Yes, we think that 5G has the unique potential to become the first global standardized system for both terrestrial and satellite connectivity with multiple use cases such as high throughput connectivity to reach uncovered areas; mobile satellite services for maritime or avionic segments; and global IoT services.

So we are developing a 5G system simulator that will be used to study and evaluate different technical alternatives and concepts, focusing especially on NTN. Active participation in standardization work is just not possible without the ability to provide relevant simulation results, and standardization will help us build even better simulation services. Our involvement in 3GPP standardization work is also related to our EU Horizon 2020 R&D projects, which have as a target the successful standardization of 5G NTN as well as its potential enhancements in future 6G.

Besides R&D and standardization support, what else do you offer the industry?

In addition to standardization and R&D activities, the service can be used as a demonstrator for SatCom companies to show to their customers and operators. They are able to demonstrate the capabilities of their existing and even future features and networks. That’s the benefit of simulators: you don’t need to

have the network when you are building the scenarios, have to evaluate what key metrics to follow, how many users you will have, how many or what kind of satellites you will use, and whether you will use 5G standards, DVB-S2 or otherwise.

And can your simulators also be useful for the emerging megaconstellation players such as Space X?

Indeed, there is a need to produce satellites within much shorter time frames, which makes more streamlined design and simulation processes necessary. A more efficient simulation workflow is also required due to the changes in the satellite industry with the introduction of megaconstellations. Our simulation services can be beneficial for companies like Space X or OneWeb, where we could model their satellite constellation networks in specific simulators.

We can build simulators modelling the bits and pieces of their constellation, starting with the number of satellites, the orbits of satellites, but especially the satellite connectivity, in other words the protocols

that are used for communicating between the ground and the satellites. Our service helps our customers experiment and understand how many satellites are required, what orbits should be used, what air interface protocols should be used to optimize link performance, and what kind of advanced radio response management algorithms should be implemented into their systems so that they can optimize their network capacity.

So would you say you’re already looking to bridge the gap between “earth” and “space” to enter the 6G era?

Definitely! Simulations are a great tool to make it happen.

“Network simulations enable the execution of reliable simulations without extensive development processes.”

“In the past, simulators have been very difficult to use.”

“Our simulation services can be beneficial for Space X or OneWeb.”

The first GSM network was launched in China in 1995, do you think it helped accelerate standardization activities in China?

The history of mobile communication network development – which represents vital infrastructure in human society – seems like a myth, following Moore’s Law from the first generation of 2C to the fifth generation of 2B in only 40 years. During this process, the second generation of mobile communication technology, such as GSM, realized the digital revolution of mobile communication itself and raised the curtain for the rapid and dazzling development of broadband mobile Internet. The fundamental logic of this story might be that, for a mobile communication industry with almost unlimited business prospects, its limiting factors seem to be only radio spectrum and enabling technology. Therefore, it continues to attract high-intensity technological innovations and investment of capital.

After signing the cooperation agreement between ETSI and CCSA

Almost synchronized with the development process of mobile communications is China’s opening-up to the outside world and the shift to market-oriented economic system reform, which led to the rapid development of China’s economy and the rapid release of the energy of China’s huge single market. With the opening of the first GSM network in China in 1995, the bulk of the Chinese

market chose GSM technology. GSM has achieved great success in China, and at the same time, it has aroused the active support and investment of Chinese industry in the follow-up mobile communication technology standard innovation activities, which is reflected in the increase in the contribution rate of Chinese enterprises to the core patents of 3GPP standards. CCSA, as one of the Organizational Partners of 3GPP, is deeply impressed by this.

You have a long-standing relationship with ETSI, what is your role and your involvement with us?

My relationship with ETSI began when I met D.G. Karl-Heinz Rosenbrock, in the late 1990s when I was the director of RITT, the Communications Standards Institute of MPT China. His introduction to the organizational structure and working mechanism of ETSI was essential for us to envision the future work of CCSA at that time. And his motto as the manager of the standards organization taught me the word “compromise”. I kept going to borrow “good ideas” from ETSI until the current age of D.G. Luis Jorge Romero, and I gained several from both of them. In return, I shared with my ETSI colleagues

something likely from the CCSA side, e.g. the special workflow of our vertical industry members to develop their own standards for their IoT applications. IoT applications represented by 5G2B are a completely unfamiliar challenge to ICT enterprises all over the world. It will be of great value for standardization organizations in different regions for exchanging experiences and the lessons gained from their own practice.

In my opinion, the more profound significance of the cooperation between CCSA and ETSI is that the deep understanding and trust of the two organizations can help their members understand each other’s members, industry and each other’s countries, which may go beyond the scope of standardization activities themselves. Although the fundamental orientation of ETSI is to serve the cause of ICT technological innovation and standardization in Europe, because of its global openness, it plays a particularly important role in the ecological environment of global standards. For example, 3GPP has created great commercial success with 3G and 4G mobile communication technology and opened the 5G2B mobile communication technology era in just 20 years. I must say that the special role played by ETSI in 3GPP is obvious to all Organizational Partners.

Over your career in standardization, have you seen any benefits for your country from this worldwide cooperation?

I think there are many reasons for Chinese industry to welcome the broadest cooperation in the global standard-setting activities of the ICT industry. First of all, China’s industry has been investing heavily in its efficient innovation system, and the resulting R & D results can directly contribute to future international common standards.

Secondly, the performance-to-price ratio of China’s products is sufficiently competitive in the market. Of course, we hope that the common standards formed through the broadest international cooperation can assist the formation of the largest single market, and we do not want to see the market divided.

From my understanding of CCSA member units, most Chinese enterprises welcome or even look forward to high-level competition. Fair competition between the best peers in the industry makes it possible to have a unified standard encompassing the best technical solutions, which is the fundamental source of standards for market acceptance and huge new value for end users, and the only way for ICT enterprises to succeed in their own businesses. In this regard, CCSA member companies are very confident in their abilities.

What are the key ICT technologies your standards research will focus on in the coming years?

In the light of the commitment and mandate of CCSA to revolutionize industries through paving the way for the standardization of the digital economy, we are currently looking at several technological trends which were considered essential components to bring industry – as well as human society – to the next level of prosperity and sustainability.

These trends include 5G Advanced toolkits, which consist of the Ultra-Dense Networking, Re-configurable Intelligence Surface, Further Uplink Enhancements for Verticals, Mesh Networking, NR based Massive Connection, and intrinsic AI, which is certainly what the communication industry is pursuing by taking advantage of the outcomes of AI in information industry. Another trend is the exciting but challenging goal of Carbon Neutrality. For instance, Solar Powered Infrastructure, Advanced Cooling System or Energy Harvesting.

I would like to take this opportunity to express my sincere thanks to my ETSI colleagues who have worked with me happily and helped me.

Quality of experience: a key requirement for end usersAware of the importance of speech transmission requirements from the perspective of a user’s quality of service, ETSI sets standards for handsfree, handset and headset VoIP terminals, in narrowband and wideband.

Standards relating to terminals and networks for speech and media quality, end-to-end single media and multimedia transmission performance are essential for end users. The ETSI Technical Committee on Speech and multimedia Transmission Quality (TC STQ) successfully handles these standards. It also develops Quality of Service (QoS) parameters for networks and services and Quality of Experience (QoE) descriptors and methods. To ensure alignment with other standard-setting organizations and facilitate industry implementation, the group provides guidance and background information on effectively applying the standards and methods created.

As well as creating a large number of standards for speech transmission requirements, the committee has developed a specification offering guidance and detailing the methodology to objectively assess the listening effort required by a user during a voice call.

The committee has also standardized subjective and objective methodologies for the qualification and performance requirements of the new ETSI speech codec for encoding and decoding digital speech signals, in cooperation with the DECT (Digital Enhanced Cordless Telecommunications) group.

Measuring 5G performanceTo meet the requirements of mobile networks, the subgroup STQ Mobile focuses on QoS and QoE aspects for popular services in mobile networks, as well as parameters and test scenarios for assessing network capabilities in 5G performance measurements. STQ Mobile liaises with 3GPP and other standards organizations to support the development of methods and equipment used for characterizing existing and future network telecommunications services, both landline and mobile. Several of its

standards and reports are the basis for ITU-T SG12’s own work.

Successful global implementationNational mobile network benchmarking and scoring campaigns are of great importance to mobile network operators. ETSI has therefore developed TR 103 559 to meet these requirements, with regard to the area and population to be covered, the collection and aggregation of test results, and the weighting of the various aspects tested. The report takes into account the rapid development of mobile technology and the consumer habits of users, as users’ quality of experience changes over time, by parameterizing individual factors that contribute to the score.

The tests assess telephony, video streaming, data throughput and more interactive applications such as browsing, social media and messaging. The results collected from the various areas are individually and collectively weighted and summarized by an overall score.

For greater authority, the scoring methodology is based on a set of standardized market KPIs and provides governance and implementation principles as well as concrete realizations. TR 103 559 describes its scoring method with full transparency for the benefit of implementors, network providers and regulatory authorities, and has been applied on a global scale.

In celebrating its 30th Anniversary, the time has come to look back over GSM. Much of what we take for granted today is the result of this big bang in ICT history. Let’s have a quick review of some of these principles that constitute our foundations today and guide our evolution in the future. Without GSM, we would probably not be talking about 5G or 6G as we do today. So “what has GSM ever done for us?”

A tribute to GSM: 30th Anniversary of GSM’s first call

Design principles set the groundworkWhether you call them design principles, or fundamentals, or “constraints imposed by the conditions of the environment”, the development of GSM followed a series of requirements that today constitute the basis of the design of our new systems, which nobody would challenge.

First, the system had to fit the requirements of many different countries. It needed to be a joint effort and decisions had to be taken based on consensus. Every interested party played a role in the definition and development of the system, starting with governments and administrations, which had to create the proper environment for the system to land and grow, but also the operators who would have to deploy and run the system and, lastly, the manufacturers that would need to develop it.

The conditions for all these stakeholders to work together had to be agreed upon. Cooperation and consensus building became undisputable principles.

Bearing in mind the stated requirements, the system to be developed had to be modular, fitting into a commonly agreed architecture where the key interfaces -which would eventually define how the system would be developed, built and operated- needed to be carefully specified. With this system, every single piece of the puzzle could fit with the rest,

regardless of who had produced it. This meant that full networks could be built and further expanded using pieces from many different manufacturers, which would foster competition. And one of the important pieces here was the mobile terminal itself. Now, various manufacturers could produce handsets that would operate on all networks.

Interoperability became then a vital concept.

Another very relevant concept developed at this time was the split between the user identification and the terminal. The birth of the SIM card. The rights of a customer to use the network would be associated

to a SIM card, under a standardized form factor, that would fit in all available mobile terminals. In this way, a user could easily swap terminals with no need to make changes in the operator’s databases. This provoked huge new dynamics in the marketplace and a great variation in the availability of mobile terminals, which now develops devices from sensors to smartphones, to cars and beyond.

The split between the subscription and the terminal used turned out to be fundamental.

Cooperation, consensus building and interoperability became undisputable principles.

One of the biggest challenges of existing mobile telephony was fraud and security. It was easy to clone handsets, tamper with users’ identities and listen to conversations over the air. In leveraging the SIM card -as well as through other means- GSM was designed with

security in mind; making the cloning of SIM cards extremely complex (as it is not only the SIM card that supports the user’s credentials) and cyphering the communications. When communications are cyphered and the identity of the users protected, law enforcement bodies must be enabled to intervene if required by the authorities. The means for lawful interception are also embedded in GSM.

We could say that the concept of “security by design” started to settle with GSM. The means to enable law enforcement agencies to perform their duties as required by the authorities were also developed.

Another important concept that started with GSM is that the system was designed to offer services beyond mobile telephony. At the time, voice was the main means of communication. With GSM, mobile data started to be enabled. But, most importantly, technology provided additional hooks to enable the creation of value-added services, like SMS, cell broadcast, etc. Not all of them worked from the start but making these technologies available allowed the market to devise new uses and business models.

Mass market along the wayHaving designed a flexible, scalable, multi-vendor system that was embraced by EU member states from the beginning, GSM was able to achieve fantastic economies of scale from very early on, a phenomenon never before experienced in mobile telephony. But a few barriers still had to be broken to unleash the full potential of the technology.

First, the spectrum of use for this technology had to be harmonized. GSM was to be a pan-European system, adopted by all member states. It would have to enable a single system all throughout Europe. Borders would need to be removed, and terminal equipment should be able to cross them freely. Type approval of devices had to be homogenized across the different nations and was eventually replaced by a self-declaration of conformity from the manufacturers, which enabled much faster and cheaper access to market.

With all this, another advancement was to become fundamental. To make of it a truly pan-European system, customers from an operator in one country should be able to connect to the system beyond the boundaries of their own operator. International roaming was institutionalized: operators would set

the conditions so that customers from one operator would be able to receive service from another operator.

With the explosion in demand and the ease of swapping devices, service providers envisaged new ways of bringing more customers to their networks. Two initiatives are worth remembering: the subsidization of mobile terminals in exchange for long-term subscriptions and prepayment schemes. Both were fundamental in growing the subscriber base and bringing mobile services to most of the population, and both leveraged the technological capabilities that GSM provided.

Another aspect which is important to highlight is the changes to the business

model, where voice was no longer the only service bringing in revenue. The quest for different value-added services and sources of income was starting -and has been expanding since. In this search, one lesson learned is that value could come from unexpected sources: manufacturers and service providers were no longer the “only source of wisdom”. The mass market being addressed, this further pushed the need to seek additional sources of revenue by envisaging mobile connectivity solutions tailored to different sectors.

A growing ecosystemGSM sparked a very profound change in the environment and the ways in which we behave. In the very early days of mobile telephony, pre-GSM, a mobile phone was a luxury device only available to the very wealthy. Its value was still to be proven.

With GSM and its evolution, being connected everywhere and at all times has become a basic need. Like water or electricity. People might leave home without their wallet, but never without their mobile. Our device contains all we need for our daily lives: it is not just a communication device but connects us to (and integrates us in) the society. Our files, our pictures, our videos, our entertainment, our games, our contacts, our payment means… everything is there. Going beyond mobile telephony itself, it is also a fundamental tool for many economic sectors’ productivity.

Our behaviour, our economy, our society at large is hugely influenced by what GSM started.

Furthermore, the way in which we now understand how our world of communication develops stands on the foundations that GSM set: global cooperation and high-quality standards that embrace the latest developments from research and the requirements from the market are key.

GSM was an achievement beyond the technology itself. The GSM standard allowed billions of people to access mobile services and communicate with each other. It was the starting seed for many new approaches which have enabled and given birth to various new initiatives and improvements. It provided the encouragement to try and fail (as the impact of the blow would be softened by everyone taking it) and the willingness to accept and embrace great ideas, no matter their origin. GSM sowed the seeds of our very rich and fast-growing ecosystem.

Yes but, apart from this, “what has GSM ever done for us?”

SMS

The invention of texting In the mid-1980s, mobile phones were huge and battery hungry. People carried radiopagers so that they could switch off their phone to save battery. These radiopagers evolved to allow short text messages to be received so that customers would know why someone was trying to contact them.

While the first digital mobile radio system for Europe was being developed, the idea came from a Franco-German paper to integrate this kind of capability into the mobile phones themselves using digital signalling. This eliminated the need to carry a radiopager as phone battery consumption was improving significantly, and people could now leave their phones switched on.

This led to the detailed development in ETSI of the technical specification for SMS. Messages were collected in an SMS ‘Service Centre’, and delivery was

attempted via the mobile network to wherever the device happened to be. There was a retry capability in case the device was out of coverage or switched off. And then there was the ability to generate a message from the device itself, even if nobody believed that this would be useful for the mass market as keying in a text message using a mobile phone keypad would be too arduous for most people.

The length of the short message was a key discussion point at the time. Alphanumeric pagers were limited to 90

characters, so it seemed plausible to aim to double that to 180 characters. Unfortunately, the signalling packets defined by the ITU Blue Book, after taking away the overhead, limited the length of the short message to 140 bytes. This was still felt to be a reasonable goal and, due to the clever idea of using 7 bits per character instead of 8, was increased to a 160-character limit. ETSI later allowed for longer messages, increasing the number further by splitting the text into several message packets.

In time, mobile phone manufacturers improved their interfaces so that keying in text messages became easier and operators – seeing the market uptake and its potential – began offering SMS at low cost or for free. Yet mobile networks were interconnected for voice but not for text. It took a couple of years for operators to develop the community by providing interconnectivity for SMS. This, together with lower cost subscriptions, further opened up the use of SMS for younger people, who soon developed the new youth led shorthand language. And so texting was born.

ETSI played a key role in the development of the standard for SMS but also in the development of young engineers with great knowledge of how the system worked and enthusiasm for the new medium.

A Security Token for GSMThe work on standardizing a security token for mobile equipment (or handsets) for the GSM system started in January 1988. The name of the token, the Subscriber Identity Module (or simply SIM), was there from the very beginning, though it was not quite correct as, in the end, it would only verify the identity of the subscription and only indirectly that of a subscriber. There were initially three proposals for a SIM: a fixed solution incorporated into the mobile equipment, a smart card the size of a credit card already used in an existing analogue network, and something called a Plug-in SIM.

The fixed solutionThe fixed solution meant incorporating all the security into the mobile equipment. Network operators had their own specific authentication algorithms and keys unique to each subscription. A fixed solution would require a (standardized?) loading mechanism for the algorithm and keys, as well as a mechanism for replacing such an algorithm or the original key. Storing secret information like keys and algorithms somewhere in the memory or software of a mobile equipment was

a major concern. How could the network operator be assured of the security of its secret information? A fixed solution was not considered feasible at the time, and it would have also constituted a trade barrier for mobile equipment.

A credit card type-but what size? The idea of a credit card-type SIM was quite popular with some operators in the

early days when mobile phones were the size of a brick. It was thought that subscribers might have a SIM but no phone, and this SIM could also serve as an (embossed) credit card.

Well, this never materialised and the dramatic reduction in handset size meant that it was the third format, the Plug-in SIM, that became the ‘standard’ type. It was the same as the credit card-type SIM except for its smaller size of 15 mm by 25 mm.

By repeatedly cutting away ‘excessive’ plastic, the third and fourth form factors – better known as the micro-SIM and Nano-SIM, respectively – emerged. With the latter, the miniaturization of the SIM card had reached its peak – it could not be made any smaller without making changes to the physical interface.

EvolutionTowards the very end of the last millennium, ETSI had started to work on a smart-card platform called the UICC.

The idea was to separate the basic functionality and security features from the applications so that different applications such as the SIM (and others, e.g. those used for payment or identity purposes), could reside side by side on the same platform.

When 3GPP was founded, an agreement was reached whereby the work on this smart-card platform already started by ETSI would stay with ETSI (TC Smart Card Platform was founded for this purpose) and only the specific application part, the SIM application, would move to 3GPP. During further development of the UICC, the idea of a fixed UICC (SIM) underwent something of a revival.

In 2010, TC SCP specified a solderable UICC for M2M purposes. Instead of being embedded into a piece of plastic, the chip containing the UICC was soldered onto a PCB.

The idea of a general-purpose embedded UICC (an eUICC) was proposed by TC SCP around the same time and was subsequently adopted by the GSMA as the basic concept for an eSIM.

The future is now: Smart Secure PlatformThese days, TC SCP is still enhancing the UICC platform by, for instance, specifying the use of the UICC NFC interface for UWB applications. However, the main work performed by TC SCP is the specification of a new, Smart Secure Platform called SSP. This new development provides an open platform for multiple applications with various physical interfaces and form factors, a new flexible file system and built-in capabilities to support several authentication methods, as well as features such as the Toolkit or the contactless interface defined for the UICC. SSP is a highly secure, scalable – and therefore cost-efficient – solution

optimized to address many requirements, from IoT applications to complex solutions. One of the five specifications already published deals with the Secure Element as part of a System on Chip (SoC) solution. A test specification for this has also been published.

One of the main reasons for the success of GSM was the availability of a secure token, the SIM (UICC), which made the development of handsets independent of operator specific needs in that respect. This together with a complete set of test specifications ensured interoperability thus providing a nearly global market. This is summarized in a slogan from the early days:

Every SIM in every handset in every

network – worldwide.

From GSM to 3GPP ETSI standards go global! GSM was a roaring success in Europe with roaming agreements firmly established and the common use of 900MHz and 1800MHz but that was not enough for ETSI….

The beginningsIn the mid-1990s the PCS1900 phenomenon became fully established in the United States, with 3 different technologies deployed, one being GSM, but using 1900MHz instead of 900 or 1800. Manufacturers started talking about putting all three bands into one phone – the so-called tri-band handsets that would enable roaming across Europe and the United States.

Yet this was not enough for ETSI and the GSM community, so they started talking to their counterparts in Japan and Korea to see whether further advances could be made in global harmonization. Japan and Korea had already deployed narrowband Code Division Multiple Access (CDMA) systems based on the systems first deployed in the US but they were missing the detailed roaming and international working capabilities of GSM and the phones were not interoperable with European systems.

3G foundationsThe mobile industry was developing ideas around Future Public Land Mobile Telecommunications Systems or FPLMTS that would become the foundation for 3G, the ideal opportunity for a system and mobile phones with near-worldwide capacity. ETSI’s SMG5 had started to prepare specifications that would improve the radio interface, giving much faster speeds than 2G but keeping the same core network with all the interconnectivity and roaming facilities already enjoyed across many countries. Far eastern countries who were used to CDMA wanted a new, wider band version to give higher speed. ETSI agreed to work on Wideband CDMA but it became clear

that there was a political need for a new organization to promote collaborative working between regions.

3GPP was bornSo, the idea of a Third Generation Partnership Project was born. ETSI would be the European Partner and would work together with its counterparts from the US, Japan and Korea.

Delegations from these regional standards making bodies met in Sophia Antipolis in December 1998 to set out the key parameters of the 3GPP. Decisions included that standards work would be based on the model already used by ETSI for GSM, and there would be four Technical Specifications Groups developing Radio, Core, Terminals and System Aspects. To ensure a regional

balance, leaders of the groups were elected from across the original partners.

The target was to produce implementable standards within a year. All the partners worked very hard to achieve this Release 99, despite the organization being so new, with a final version approved in March 2000.

This was an incredible achievement initiated by ETSI, with engineers coming from different backgrounds to create a worldwide standard for anyone, anywhere, providing communications using voice, text and data. It offered the first mobile video calling technology and laid the foundations for the multimedia phenomenon that is used worldwide today on the vast majority of smartphones!.

Business leaders now view sustainability as a means of driving the new competitive advantage.

The growing proliferation of IoT devices and sensors represents a fundamental building block in reaching sustainability goals. There are, of course, other complementary technologies ranging from mobile network connectivity to advances in artificial intelligence and machine learning. However, what is required is a framework for interworking diverse IoT systems and technologies. Ideally, this would be based on an open and extensible standard that will promote economies of scale and adapt to new use-case requirements and future innovation.

Since 2012, oneM2M has undertaken important work on its horizontal architecture, which provides a framework for any-to-any interactions in scalable IoT systems. That means devices can communicate data to monitoring and decision-making applications, while system designers can mix and match components from different vendors.

oneM2M’s horizontal architecture also provides a reusable way for different industry verticals and the developer community to build interoperable IoT systems. This is the foundation for collecting and sharing data at scale and to do so in an interoperable manner

across compartmentalised silos and organizational boundaries.

oneM2M Sustainability InitiativeIn response to strong member support, oneM2M recently launched a sustainability initiative with activities focused on three areas. The first focus area is to drive conversations and promote ideas that illustrate the impact of IoT on sustainability.

The second focus aims to help developers build IoT systems based on sustainability principles. These include interoperability, scalability, modularity, and re-use principles which are also fundamental to the oneM2M standard. The initiative

emphasizes replicability to make it easy for users to borrow from oneM2M use cases and deployments that deliver on the sustainability agenda.

The third focus area relates to capabilities within the oneM2M technical specifications that help developers build sustainable features into their solutions. oneM2M provides a standard way to gather and send data without devices needing to be constantly on and polling the network, which is a boon for energy efficiency. oneM2M also addresses the deployment of IoT systems that combine new assets and legacy infrastructure. This preserves the value of installed systems that are still operational before their end-of-life cycle.

A personal journey: from CEPT to ETSI and back to CEPT

and vice versa. Since then ETSI TC RES and ERC Officials have met on a regular basis. In addition to GSM, a successful example of this collaboration was when CEPT, ETSI and the EU considered it crucial to have a spectrum available for a new generation of cordless telephones. As such, in 1987, CEPT founded a working group for a CEPT Recommendation on Cordless Telephones to be operated in the 1800 MHz band, which became the world-renowned ETSI DECT standard.

The ETSI TC RES, which I chaired from 1991 to 1997, soon had new standardization objectives and was split into 11 sub-technical committees and, later on, new Technical Committees, including TETRA and HiperLAN.

After working for ETSI’s groups for 10 years, I returned to CEPT, and soon became Vice-Chairman of the ECC; in 2001 I was appointed to chair the ERC from 2001 to 2007. I could then continue to meet and collaborate with my ETSI colleagues to find the best way to standardize radio technologies.

n Chris van Diepenbeek.

From CEPT to ETSIAt the end of the 70’s, the state-owned PTTs (postal services and telecommunications) were privatized and spectrum management laid in the hands of member states. When the first cellular mobile systems were launched, it became clear that spectrum harmonization would be key. Therefore, in 1982 CEPT decided to create a pan-European mobile communication system and allocated the 900 MHz band to mobile services. The standardization work was carried out within a newly founded group called ‘Groupe Spécial Mobile’ (GSM). In June 1987, when the Commission of the European Communities issued its ‘Green Paper’ on the development of the common market for telecommunications services and equipment, CEPT took the initiative to create a European telecommunications standardization institute within its own organization, noting that it should not be an intergovernmental organization. In the end, ETSI was created in 1988 as an autonomous not-for-profit association and all standardization work on GSM was transferred to ETSI.

Radio spectrum managementAlongside its Working Group GSM, CEPT managed the WG Radio Equipment and Systems (RES).

About a year later, RES was transferred to ETSI to avoid endangering progress

made in the work underway (now TC RES). I describe this transfer not as an unfortunate divorce but as ‘Living Apart Together’, as collaboration remains strong between both organizations.

CEPT created its European Radiocommunication Committee (ERC, now ECC). CEPT/ERC Decisions would replace the Recommendations where possible, with the objective being to increase the commitment of administrations. Early examples of CEPT/ERC Decisions included frequency bands for GSM, DECT, DSRR, TETRA and TFTS, which would become ETSI standards.

The European Commission steps inAround 2000, the European Commission gave mandates to the CEPT Electronic Communications Committee (ECC) to develop Decisions as an input document for their EC Decisions with regard to the mandatory spectrum for EU Countries.

The EU harmonized spectrum was required to support related standards

When I started as an engineer in a Spectrum Management Organization in 1977, I quickly became aware of the basic rules of those days: private use of radio was only allowed when necessary and for business purposes; the only relevant exception was amateur radio. The future would bring a lot of changes.

ETSI and O-RAN ALLIANCE cooperate to accelerate O-RAN adoption in EuropeAn ever-increasing traffic demand and diverse applications needs require a new approach for the 5G era and beyond.

As an industry, we have been tremendously successful at building and operating massive, high-performance wireless networks based on global standards to deliver superb connectivity services to our customers. These network builds have traditionally relied on highly specialized radio access network (RAN) equipment with tightly integrated proprietary software. To cater for the ever-increasing traffic demand and diverse consumer and industrial applications requirements, a radically new approach is required for the 5G era and beyond.

A new approach for the 5G eraThe solution is to make the mobile networks and the equipment that runs them more software-driven, open, virtualized, flexible, intelligent and energy efficient. The emergence of Open RAN therefore promises to unlock benefits from network programmability and automation for mobile operators, while stimulating a more vibrant RAN supplier ecosystem with faster innovation cycles to improve user experience.

In 2018, five operators, AT&T, China Mobile, Deutsche Telekom, Orange and NTT DOCOMO, came together to form the O-RAN ALLIANCE with the mission to re-shape the RAN industry towards more intelligent, open, virtualized and fully interoperable mobile networks.

The O-RAN ALLIANCE has since grown to become a global community of nearly 300 mobile operators, vendors and research institutions operating in the RAN industry. Today, there is very strong momentum behind Open RAN.

An open and intelligent virtualized RANThe main body of O-RAN ALLIANCE’s work is to generate an open architecture as the foundation for building virtualized RAN on open hardware and cloud, with embedded AI-powered radio control. It is made possible through standardized open network interfaces. 3GPP has been phenomenally successful in standards development. The O-RAN specifications fully support and are complementary to the 3GPP-based standards.

Similarly to 3GPP, the O-RAN ALLIANCE seeks to work with other leading global organizations to create a synergistic effort that will accelerate the development and adoption of Open RAN. ETSI has an outstanding global reputation as a Standards Development Organization and its work has contributed immensely to the digital landscape in Europe and beyond. A cooperation agreement

between the O-RAN ALLIANCE and ETSI is therefore a very significant milestone on the Open RAN journey.

A common objectiveWe already share a wide cross-section of members and a common objective to perform and promote regional and international standardization. Through our cooperation, we can build on these foundations to align our mutual interests in the standardization process for interoperable Open RAN.

Open RAN will not emerge overnight. It will be deployed gradually with some interfaces and capabilities becoming available earlier than others. And there will be regional variations in the timing of Open RAN deployments. I am convinced that the coordinated efforts of the O-RAN ALLIANCE and ETSI will be an important catalyst for a vibrant Open RAN ecosystem contributing to a great digital future in Europe.

I look forward to working with you to make this happen.

n Dr. Alex Jinsung Choi, COO of the O-RAN ALLIANCE and SVP Strategy & Technology Innovation, DEUTSCHE TELEKOM AG.

Procedures for trusted lists

Mitigation Strategy Report on Securing Artificial Intelligence The ETSI SAI ISG has recently released ETSI GR SAI 005, a report which summarizes and analyses existing and potential mitigation against threats for AI-based systems. Setting a baseline for a common understanding of relevant AI cyber security threats and mitigations will be key for widespread deployment and acceptance of AI systems and applications. This report sheds light on the available methods for securing AI-based systems by mitigating known or potential security threats identified in the recent ENISA threat landscape publication and ETSI GR SAI 004 Problem Statement Report. It also addresses security capabilities, challenges, and limitations when adopting mitigation for AI-based systems in certain potential use cases.

qualified certificates, EU qualified time stamps, evidences created by qualified electronic registered delivery services, EU qualified validation reports on EU qualified electronic signatures or seals).

Trusted lists enable in practice any interested party to determine whether a trust service is or was operating in compliance with relevant requirements, currently or at a given time in the past (e.g. at the time the service was provided, or at the time at which a transaction reliant on that service took place).

EUMS Trusted Lists have a legal constitutive value. It is the single formal source to verify that a claimed EU qualified trust service provider and the claimed EU qualified trust service it provides are indeed granted an EU qualified status by the competent EUMS body.
